VM folder removed after update

Is it possible the installer moved the folder to a subfolder somewhere?

Or maybe it set the folder invisible?

For example is all the disk space still there? Virtual machines tend to have more than a few gigabytes of storage in their container files.

If invisible, from an Applications -> Utilities -> Terminal session does the /VM show up with an 'ls' command

/bin/ls -leO@ /

For moved to a subfolder, you could try

Or from a Terminal session

find / -iname VM -type d

-OR- maybe better

sudo find / -iname VM -type d

If you mean the VM Folder in the root of the Hard disk with sleep image and Swapfile in it,

after first High Sierra installation i had it to on my Hard disk and the supplemental update

removed it. That is ok because the right Place for this Folder is in private var and not

in the root of the Hard disk.

A /vm folder is used by the operating system, and on a case-insensitive formatted operating system, the /vm namespace collides with /VM, and the operating system dispatches your virtual machine folder as a namespace threat.

Are you talking the /private/var/vm folder (where macOS keeps the swapfile(s) and sleepimage files).

Or when you say VM, are you talking about a Virtual Machine folder?

Could you be more specific?

And while most operating system upgrades do not touch any user files, it is always a good idea to have a backup (even better 2) before doing any major software upgrade (years of experience, and having been burned more than once, taught me this).

I never store my Virtual Machine folder in the System areas of the boot drive. Mine is stored on a fast, external drive to maximize storage space on the boot drive, and because the System space is no place for user data files (which is what VM guests really are).

I am sitting here in front of HS 10.13.1 and a /vm folder with swapfile0 exists. This is a APFS SSD, and the /vm folder is not hidden. There is another /private/var/vm folder that contains a 1GB sleepimage.

The operating system installer is a bulldozer, and is not going to pop any warnings about wiping out stuff that gets in its way.

I've just updated too and had a folder named VM in the root directory that has now gone.

It had 200GB of files in it. And the disk suddenly has 200GB extra free.

Is there any way to get these back? Run a few recovery tools and things don't look good...
